PLOW.

To all whom it may concern:

Be it known that I, DAVID HARVARD FLOYD, a citizen of the'United States,,and

resident of Atlanta, in the county of Fulton and State of Georgia, have invented certain new and useful Improvementsin Plows, of which the followlng 1s a specification.

This lnventlon relates to certaln improveinents in plows and more particularly to means for adjusting the plow share in respect to the beam. e

In my improved construction I pivotally connect the plow share to the beam and my invention involves the means for locking the share in position after having properly adjusted it about its pivotal connection. This locking means is preferably so constructed that it may be operated without the use of permit any relative movement of the beam' and share or any lost motion.

Reference 1s to be had to the accompanying drawings in which similar characters of reference indicate corresponding parts throughout the several views, and in which- Figure 1 1s, a perspective new of a plow constructed in accordance with my inventlon; Fig. 2 1s a slde elevation of a portlon of the beam and the plow share showing the latter in two adjusted positions; Fig. 3

is a top plan view of the parts, shown in Fig. 2; Fig. 4: ls'a perspective view of one member of the locking mechanism; and Fig."

5 is a perspective view of the'second member of the locking mechamsm.

In the specific form illustrated, the foot 10 of the standard has two branches or arms 11-11 extending upwardly and thence forwardly and disposed upon opposite sides of the beam 12. A bolt 13 or any other suitable means serves as a pivotal connection bet-ween the foot or standardand the beam and permits the lower portion or pointof the standard to swing forwardly and upwardly in a vertical plane.

I have illustrated a very simple form of plow standard but I Wish it distinctly un-,

clerstood that my invention does not relate to the construction of the lower portion of to eachother.

the standard and that any other suitable forln mightbe employed, a

My invention, involves particularly the means-for securing the'upper front ends of the arms 1l',11 to the plow beam, so as to hold the standard and beam rigid in respect Specificationof Letters lat ent. v Pa te f d J ga i T Y Application filed July 12,1913.

As shown the. front ends of the'arms are connected by a transverse pin 14 and on the upper surface of the beam is mounted a slide 15, shownparticularly in Fig. 4. The slide is mounted for movement through a limited distance longitudinally of the beam and is held'against removal from the latter. The,

lost motion attaching means preferably includes two pins 16 and 17 extending'through slots 18 and19 in the slide. The length of said slots determines the amount of end-wise pins16 and 17 prevent the removal of the slide. Theslideis provided'with one or more upwardly extending brackets iQO proenter from anedge curvedin' an'arc having ;the bolt 13 as the center so that 'they areall movement of theslide, andthe headsof the .at equal distances from thelpivotal connec 1 tion, and their opposite sides are parallel .and spaced a distance equal to the diameter of the pin The range ofmovement and the position of the slidearesuch that when it is i moved end-Wise in one direction the pin 14:

may enter anyone of the recesses and thus I .90

lock the standard against movementabout its pivot. With the slide in the opposite limiting position the pin is free from the bracket and the standard may be freely swung. i

j For positively retaining the slide in lock-Z ing'position I may employ the'locking meme .ber shown particularlyin Fig. 5. This is aneccentric head QQfor the real-pin 17 and? I disposed between-'stops23 on the upper sur-; face of the slide and adjacent opposed ends of the slot 19? lVith the eccentric in the position shown in Fig. 3 it engages with both the stops and positively"preventsthe rearward movement of the slide or the disengagement ofthe pin 14. .VVhenit is desired to adjust the plow standard the eccentric may be turned about the pin 17 as i a center by means of a flange or ridge of the upper surface of the eccentric. By turning the eccentric one-half of a revolution or possibly less, the slide is automatically moved rearwardly to such an extent as to free the pin 14 and permit the free swinging of the plow standard. It will be noted that it is only necessary to turn the eccentric to lock or unlock the plow share and that no tools of any kind are required to operate the parts. I have shown two separate brackets 20 adjacent the two arms 1l-l1, but it is evident that only one need be employed if it be made of sufiicient width and strength and a larger or smaller number of recesses 21 could be employed dependent upon the desired range of adjustment.

Various changes may be made within the details of construction, within the scope of the appended claims and without departing from the spirit of my invent-ion.

The plow is provided with handles 25 which are preferably adjustable both angularly and longitudinally in respect to the beam, but this adjusting means forms no portion of my present invention. As shown a non-rotatable circular plate 26 is secured to each of the two opposite sides of the beam and is provided with an annular row of teeth or serrations which engage with a cor responding row in a second plate 27. This. latter plate is provided with a groove 28 in its outer surface, deeper at one end than at the other so as to receive the handles and permit the desired spreading apart of the latter toward the outer ends. A clamping bolt 29 passes through both pairs of plates and through the handles, and has washers 30 bet-ween the outer surfaces of the handles and the head and nut of the bolt. The handles are provided with longitudinal slots 31 which permit of an end-wise adjustment of the handles. The outer plate 27 may have a stud projection 32 disposed within said slot, to prevent said portions from being bent toward each other or otherwise injured.

Having thus described my invention, what I claim as new and desire to protect by Letters-Patent is:

1. A plow having a beam, a standard pivoted thereto and having a forwardly extending arm, a slide: carried by said beam and having a series of recesses therein, a project-ion on said arm adapted to enter any one of said recesses and hold said arm in adjusted positionin respect to said beam, and means for locking said slide against relative movement in respect to said beam.

Copies of this patent may be obtained for five cents each, by addrcssingthe Commissioner of Patents,

2. A plow having a beam, a slide upon the upper surface thereof and having an upwardly extending bracket provided with recesses in the front edge thereof, a plow standard secured to said beam and relatively movable in respect thereto, said standard having a portion projecting adjacent said bracket and adapted to enter into any one of said recesses to lock said share in adjusted position relative to said beam.

3. A plow having a beam, provided with a slide upon the upper surface thereof, said slide having an upwardly extending bracket provided with recesses in the front edge thereof, a plow standard secured to said beam and relatively movable in respect thereto,said standard having a portion projecting adjacent said bracket, and adapted to enter into any one of said recesses to lock said standardin adjusted position relative to said beam, and means for locking said slide against movement.

4. A plow having a beam, a slide upon. the upper surface thereof, and havlng an up- ,wardly extending bracket provided wlth re cesses in the front edge thereof, a plow standard secured to said beam and relatively movable in respect thereto, said standard having a portion pro ecting ad acent said bracket and adapted to enter into any one of said recesses upon the proper 'relatlve movement of said standard and; slide .to lock said standard in ad ustedposition relative to said beam, and an eccentricrm engagement with said slide for moving the latter and locking the same against movement. a

5. A plow having a beam, provided with a slide upon the upper surface thereof, said slide having an upwardly extendmg bracket provided with recesses in the front edge thereof, a plow standard pivotally secured to said beam and having a portion projecting forwardly along said standard and terminating adjacent said bracket and having a projection adapted to enter into any one of said recesses to lock said standard in adjusted position relative to said beam, and
